With Linux 2.6.10(triton) in the gadget side we get only 1.1 Mbps(Control panel->Network Connections-Local Area Connection Status->Speed) .This was verified on Windows 2k/XP.Later we downloaded the USB gadget from Linux 2.6.14 and was getting 9.7 Mbps.What might be the reason for this?

I don't know. Try it and find out. I seem to recall another recent-ish trouble report with RNDIS, but it's not clear what was up since the last times I've tested it, it came up just fine. Maybe there's an issue specific to pxa25x_udc; I don't use that much at all any more. > 7)The same functionality is available for PXA 255 based pda's available > like Zaurus,gumstix,ipaq,yopy .Does thay use the same drivers in Windows XP > distribution and the device side stack. They all use more recent Linux kernels than 2.6.10 as I recall, and yes they all try to use the stock XP drivers. - Dave ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
